Legality of polygamy

The legal status of polygamy varies widely around the world. Polygyny is legal in 58 out of nearly 200 sovereign states, the vast majority of them being Muslim-majority countries. Some countries that permit polygamy have restrictions, such as requiring the first wife to give her consent.

In countries that ban polygamy, the offence is commonly called bigamy, though the penalty varies between jurisdictions. In some countries where polygamy is illegal, the prohibition is not enforced.

Africa
Polygamy is more widespread in Africa than in any other continent, being most common in a region known as the "polygamy belt" in West Africa and Central Africa, with the countries estimated to have the highest polygamy prevalence in the world being Burkina Faso, Mali, Gambia, Niger and Nigeria. In the region of sub-Saharan Africa, polygyny is common and deeply rooted in the culture, with 11% of the population of sub-Saharan Africa living in such marriages (25% of the Muslim population and 3% of the Christian population, as of 2019). Polygamous marriages occur, regardless of legality, as the practice is deeply rooted in culture and often supported by Islam in Africa.

 * 🇧🇷 Brazil: Bigamy is illegal. The marriage of a single individual to more than one other person is prohibited by law as bigamy, which is punishable by two to six years of imprisonment, and is valid for every Brazilian citizen, including naturalized ones. De facto polygamy is not outlawed.
 * 🇨🇦 Canada: All forms of polygamy, and some informal multiple sexual relationships, are illegal under section 293 of the Criminal Code. Bigamy is banned by section 290. However, as of January 2009, no person has been successfully prosecuted, i.e. convicted, in over sixty years. In 2009, two acquittals on polygamy charges, arising out of the town of Bountiful, British Columbia, prompted the government of British Columbia to pose a reference question to the Supreme Court of British Columbia (i.e., the superior trial court). The reference questions asked if the criminalisation of polygamy was consistent with the Canadian Charter of Rights and Freedoms; and, if so, under what circumstances could people be legally punished for polygamy. In November 2011 the court released its 335-page long decision, which was that the criminal offence of polygamy is indeed constitutional, but that it should not be used to prosecute minors for having taken part in a polygamous marriage. Chief Justice Robert J. Bauman conceded that there is a conflict between this law and some civil rights principles, but stated that there are other and "more important" issues which in this case take precedence. He wrote (as quoted by CBC News ): "I have concluded that this case is essentially about harm. More specifically, Parliament's reasoned apprehension of harm arising out of the practice of polygamy. This includes harm to women, to children, to society and the institution of monogamous marriage." Bauman argued that there are cases where the "wives" (who may be rather young; sometimes as young as 12 years) are abducted and abused, but because they believe in faith-promoting polygamy, they are not willing to bring complaints to the authorities. He reasoned that these offences sometimes may be stopped by applying anti-polygamy legislation. The decision was welcomed by the Attorney General of British Columbia, and by a representative for the group Stop Polygamy in Canada. Likewise, according to CBC News, some polyamorous groups in Canada expressed their relief since Bauman had stated that the law shouldn't apply to them unless they decide to formalize their unions. Women's rights were central to the decision.

 * 🇪🇺 European Union: Polygamy is illegal in all 27 states. In Bulgaria, polygamy is illegal and punishable with up to three years imprisonment. In Finland, the official prosecutor is obliged to take all cases to a court where more than two persons are married to each other and such relationships cease to exist after the court has decided it. Polygamic marriages performed abroad may be recognized only on narrow occasions, for instance in child custody matters. In France, polygamy is illegal under Article 433-20 of the Penal Code and punishable by one year's imprisonment and a fine of €45,000. In Germany, polygamy is illegal, legally punishable with fine or prison time up to three years. Polygamous marriages contracted abroad are legal, however, the German authorities announced plans to close this legal loophole by making it a barrier to naturalization. In Ireland, the Catholic Church in Ireland allowed someone with a church annulment but no civil annulment to remarry in church; such a marriage was legally null and bigamous but no prosecutions were brought. The practice ended after the 1996 legalisation of divorce. In 2017, the Supreme Court ruled that if someone had two legal marriages abroad, only the first was legal in Ireland, though 'that did not necessarily mean [the second] marriage "can never have legal consequences [in Ireland]"'. In the Netherlands, a marriage between more than two individuals is prohibited; however, a samenlevingscontract may include more than two partners. It legally accepts immigrants who are in such a union from a country where it is legal; e.g. if a man with two wives immigrates to The Netherlands, all three will be legally recognized. In Romania, bigamy, defined as marriage conducted by a person who is already married, is punishable by up to 2 years in prison or fine. Knowingly marrying a married person is punishable by up to 1 year in prison or by fine. In Sweden, a person who is already married is not permitted to enter into another marriage. In the past, Sweden generally recognized polygamous marriages performed abroad. However, the Swedish government decided to task an inquiry chair with reviewing how to prevent recognition of foreign polygamous marriages in Sweden; Deputy Minister for Justice, Heléne Fritzon stating that "Polygamous marriages should not be recognised in Sweden and we need to review the existing legal loophole that makes it possible. Polygamous marriages undermine gender equality and, according to the UN, it can have serious emotional and financial consequences". Since 2021, Sweden no longer recognizes foreign polygamous marriages, save in exceptional circumstances.

Current legislation
In most countries, a person who marries a person while still being lawfully married to another commits bigamy, a criminal offence, though penalties vary between jurisdictions. Besides, the second and subsequent marriages are considered legally null and void.

The United Kingdom, Australia, and New Zealand permit some benefits for spouses of polygamous marriages performed abroad. In the past, Sweden used to recognize polygamous marriages performed abroad; but since 2021, Sweden no longer recognizes such marriages, save in exceptional circumstances. In Switzerland polygamous marriages conducted abroad may be accepted or rejected on a case-by-case basis; see § Europe.

In Canada, both bigamy (article 290 of the Criminal code of Canada) ) and de facto polygamy (article 293 of the Criminal Code) are illegal, but there are provisions in the property law of at least the Canadian province of Saskatchewan that consider the possibility of de facto multiple marriage-like situations (e.g. if an already married person enters into a second common-law relationship situation without first obtaining a legal divorce from their existing spouse).

The vast majority of sovereign states with a Muslim-majority population recognize polygamous marriages: these states span from the West Africa to Southeast Asia, with the exceptions of Turkey, Tunisia, Albania, Kosovo and Central Asian countries.

Predominantly Christian nations usually do not allow polygamy, with a handful of exceptions such as the Republic of the Congo, Uganda, and Zambia.

Almost a dozen countries that do not permit polygamous civil marriages recognize polygamous marriages under customary law. All the northern states in Nigeria governed by Islamic Sharia law recognize polygamous marriages. The autonomous regions of Somaliland and Puntland in northern Somalia also recognize polygamy, as does the country's Transitional Federal Government itself, since the country is governed by Sharia law. The recently independent country of Southern Sudan also recognizes polygamy.

Polyandry is de facto the norm in rural areas of Tibet, although it is illegal under Chinese family law. Polygamy continues in Bhutan in various forms as it has since ancient times. It is also found in parts of Nepal, despite its formal illegality in the country.

Debates of legalizing polygamous marriages continue in Central Asian countries.

International law
In 2000, the United Nations Human Rights Committee reported that polygamy violates the International Covenant on Civil and Political Rights (ICCPR), citing concerns that the lack of "equality of treatment with regard to the right to marry" meant that polygamy, restricted to polygyny in practice, violates the dignity of women and should be outlawed. Specifically, the reports to UN Committees have noted violations of the ICCPR due to these inequalities and reports to the General Assembly of the UN have recommended it be outlawed.

Some countries where polygamy is legal are not signatories of ICCPR, including Saudi Arabia, United Arab Emirates, Qatar, Oman, Malaysia, Brunei and South Sudan; so that ICCPR does not apply to these countries. It has been argued by the Department of Justice of Canada that polygyny is a violation of international human rights law.

Notable legislation
The tables below cover recent pieces of legislation that have been either debated, proposed or voted on; all of which concerns a form of polygamous union.
